I'm looking for a way to implement the "any" and "all" tests for arrays. I've discovered the any() and all() subroutines published by Graham Barr in File::Utils. To recap: 
  # One argument is true

  sub any { $_ && return 1 for @_; 0 }

  # All arguments are true

  sub all { $_ || return 0 for @_; 1 }

But it isn't clear to me how to generalize this approach for more complicated expressions, such as "are all elements of my array equal to scalar 'foo'" and "is any element of my array equal to scalar 'bar'". I suppose I could say something like 
# One argument is true

  sub any { $_ == 'bar' && return 1 for @_; 0 }

  # All arguments are true

  sub all { $_ == 'foo' || return 0 for @_; 1 }

But is that really the best I can do? I might like to have something like 
if (all (@array == 'foo')) {

Or is that asking for too much?
